The latest software blanking tests were also a success, so we'll start putting older pre-hardware-blanked data into production, now that we can remove the radar. Yay! May take a few days to rev up this engine. Meanwhile Eric has been making progress on the "zone RFI" rejection software/algorithms, so we can start getting rid of the garbage that makes up our current "top candidates."

The mysql replica was pretty much rendered useless by all our poking and prodding last week. We'll recreate it from scratch tomorrow (we hope). We are still concerned that we suddenly don't have a reliable backup mechanism, if mysqldump occasionally gives us dumps containing hidden syntax errors!

In the past had several machines that required the same updated database (a fairly large database) in multiple locations. I found that it was easier update the Master, then shutdown MySQL and make a copy of the DB and then burn to a CD for transport. Then mount the DB on the machines at the other sites. In that case the CD became my backup.Please consider a Donation to the Seti Project.

Good idea, except I'm sure the DB is a bit big for backups on CD. Perhaps a couple of removable TB drives though.

That (usually) works for MyISAM tables, but it's a bit more risky with InnoDB tables (which I think BOINC prefers for throughput reasons). Also, if you install a DB software upgrade which makes some important internal structural change, your backup - and even the live tables - might be rendered useless (though this is only likely with a major version upgrade).Stats site - http://www.teamocuk.co.uk - still alive and (just about) kicking.

This is great news. Does this mean that there will be more ap work so that people that like ap work can crunch that instead of mb work? Or have I missed the point as to why the demand for ap work is a lot higher? Thanks feel the update. New data that we will be processing soon will it be around the same processing speed or will there be a slight speed increase due to the angle it was recordered on?

matt, as always, thankyou for the update. i always enjoy reading them.

can i axk you a question. i have heard talk of seti possibly running out of work unless the blanking deal gets worked out. if you by chance do not get it worked out, is there any rough timeframe for when the work will run out. and if you do get the radar blanking deal working and fully operational, where would that put us in a timeframe for running out of data?

reason i axk is most my machines only run a few hours per day. i have my work queue set to 2 days on the temp machines. if were going to run out od workunits anytime soon i would propbably bump this up to 10.

Matt,
Thats really great news. This is science progress, SETI science progress. It gives me great hope in my heart to believe that yourself and Eric are getting to a stage where real data analysis can be carried out.
